“…At the beginning the domain kinetics in SBN was studied using decoration by nematic liquid crystals. 10 Recently, electro-optic imaging microscopy has been used for investigation of micron-scale domain nucleation and growth in SBN61 single crystals by dc electric-field pulses. [11][12][13] The high-resolution methods can be applied for studying the static domain structures only, while optical methods cannot provide in situ domain visualization with nanoscale resolution.…”

We have studied the ferroelectric nanodomain formation in single crystals of strontium barium niobate Sr0.61Ba0.39Nb2O6 using piezoelectric force microscopy and Raman confocal microscopy. The nanodomain structures have been created by application of the uniform electric field at room temperature. Four variants of nanodomain structure formation have been revealed: (1) discrete switching, (2) incomplete domain merging, (3) spontaneous backswitching, and (4) enlarging of nanodomain ensembles. Kinetics of the observed micro- and nanodomain structures has been explained on the basis of approach developed for lithium niobate and lithium tantalate crystals.

“…In the PFM experiment conditions, the electric field is strongly localized and inhomogeneous. A microscale domain state in SBN crystals was observed by electrooptic imaging microscope [18,19] and the NLC method [20,21]. The NLC method involves averaging over macroscopic scale and this enables as to correlate the domain structure dynamics with the macroscopic characterization techniques; switching current, hysteresis loop, and dielectric permittivity measurements.…”

Effect of Ni doping on ferroelectric and dielectric properties of strontium barium niobate crystals

The influence of Ni doping on the ferroelectric and dielectric properties have been examined in Sr 0.61 Ba 0.39 Nb 2 O 6 (SBN:61) relaxor crystals. The dopants introduced into SBN:61 crystals promote the switching process by reducing the value of threshold nucleation field, and thus coercive field. We present real-time studies of domain nucleation and growth processes in doped SBN:61 by the nematic liquid crystal (NLC) decoration technique. The broad phase transition and low-frequency dielectric dispersion that are exhibited by doped SBN:61 samples have a strong link to the configuration of the ferroelectrics microdomains, which in turn is strongly determined by Ni ions concentration.

“…The domain structure of pure SBN crystal was studied in details [3][4][5][6][7]. It has been shown [7] that doping with Cr impurities results in domain structure refinement, but have small effect on the domain shape.…”

Polarization Distribution and Domain Structure in SBN Crystal Doped by Eu or Rh

et al. 2010

The pyroelectric coefficient distribution representing the polarization depth profile of both poled and depoled SBN crystals doped with europium or rhodium was determined. The domain structure of polar and nonpolar cuts was also examined in these samples. It has been shown that for poled crystals Eu or Rh doping leads to higher homogeneity of polarization distribution in the bulk of the sample as compared to pure SBN. It has been revealed that the domain pattern in SBN doped with Eu or Rh differs from the one in pure and Cr-doped SBN.
